We experimentally demonstrate degenerate, forward four-wave mixing effects in a self- defocusing photorefractive medium, in both one and two transverse dimensions. We …

The physics of the photorefractive effect is briefly discussed. A coupled-mode theory is then developed to analyze the coupling of two coherent electromagnetic waves inside a …

In this letter we demonstrate and explain the lack of spatial information crosstalk between beams in various oscillators by photorefractive CPR) wave mixing (WM). 1, 2 This study is …
We investigate propagation of light beams in photorefractive media by direct numerical simulation. The two dimensional model is based on solution of nonlinear material equations …

A theoretical and experimental study of the temporal response of photorefractive two-and four-wave mixing processes is given. We examine the buildup and the decay of the output …

Self-defocusing of a Gaussian light beam in a bulk photorefractive BaTiGl crystal is demonstrated. This is a low light intensity process which results from the coupling and power …
A method for exact solution of the stationary holographic degenerate four-wave mixing in reflection geometry in photorefractive media is presented. The effects of pump depletion and …
